Whirlpool Drain Pump Chopper (W11497943)

The Whirlpool Drain Pump Chopper helps move wash water out of the dishwasher. It includes a chopping section that breaks up food particles before they reach the drain path. This can reduce clogs and help the unit drain at the right time in the cycle.

Failure can happen from hard debris jamming the chopper area, worn or damaged blades, or a pump section that cannot move water at full flow. Seals and internal parts can also wear over time. When this happens, water may not leave the tub, or the dishwasher may stop mid-cycle to prevent overflow.

Symptoms that can point to a problem with the drain pump chopper include:

• Standing water left in the bottom of the dishwasher after the cycle ends
• Slow draining or draining that stops and starts
• Unusual grinding, rattling, or buzzing sounds during drain periods
• Dirty water returning to the tub after draining
• Cycle stops or ends early when the unit tries to drain
• Water leaks near the pump area after a drain attempt
